Life History And Laboratory Rearing Of Corythucha Juglandis (Hemiptera: Tingidae) With Descriptions Of Immature Stages, T. E. Vogt, J. E. Mcpherson

The Great Lakes Entomologist

The life history of Corythucha juglandis was investigated in Jackson and Alexander counties. Illinois. August 1981-December 1985 and the immature stages were described. The bug was also raised from egg to adult under controlled laboratory conditions. This apparently bivoltine species overwintered as adults that became active in late April-early May. began feeding on the undersides of black walnut leaflets, and reproduced shortly thereafter. The seasonal occurrence of the adults and subsequent immature stages is discussed. Adults were last observed in mid-October. C. juglandis was reared on black walnut leaflets under a 16L:8D photoperiod at ca. 23.9°C. The pre-ovipositional, ovipositionaL and …

Life History Of Neoplea Striola (Hemiptera: Pleidae), J. E. Mcpherson

The Great Lakes Entomologist

The life history of Neoplea striola was studied in southern Illinois during 1983-1985. This apparently univoltine species overwintered as adults and became active in early March. First instars appeared in mid-May followed by marked overlapping of the subsequent instars. No active adults were found after November.

Antennal And Mouthpart Sensilla Of The Blister Beetle. Meloe Campanicollis (Coleoptera: Meloidae), R. G. Bland

The Great Lakes Entomologist

Sensilia on the sexually dimorphic antennae of the blister beetle, Meloe campanicollis, were primarily sensilla chaetica with scattered socketed and non-socketed sensilla basiconica. Forked chaetifonn sensilla on the female's first segment are displaced by the antennal socket rim when the male grasps and lifts her antennae with segments 5 to 7 of his antennae. Segments 5 to 7 lack dense sensilla chaetica and have only patches of shorter sensilla. The segments also contain a high density of epidennal gland ducts compared to other segments. Maxillary palpi apices were similar in males and females, but the female's labial palpi contained …

Epinotia Nisella: An Unrecorded Host And Mode Of Feeding (Lepidoptera: Tortricidae), William E. Miller

The Great Lakes Entomologist

The larva of Epinotia nisella is best known as a feeder in female catkins of Populus, primarily P. tremuloides Michx. in North America. In Minnesota, adults were reared from larvae boring in current-growth branchlets of P. balsamifera L., with no sign of like infestation in neighboring P. tremuloides, which has thinner branchlets. The behavioral variance is explained as plasticity in feeding biology, a characteristic of insects utilizing host reproductive structures whose abundance is periodic.

Dufourea Novaeangliae In Illinois, With Confirmation Of Host Plant (Hymenptera: Halictidae), John K. Bouseman

The Great Lakes Entomologist

(excerpt)

Dufourea (Halictoides) novaeangliae was described (as ,i>Panurgus novaeangliae) by Charles Robertson (1897) on the basis of two males from Connecticut and Massachusetts. Viereck (1904) redescribed the species as Conohalictoides lovelli from material of both sexes taken from flowers of pickerelweed, Pontederia cordata L. (Pontederiaceae), by J. H. Lo.elI at Waldoboro, ~laine; he also mentioned a male from Pennsylvania and a female from .\Ianland.

Social Wasps Of The Huron Mountains, Michigan (Hymenoptera: Vespidae), Mark F. O'Brien

Ten species of social wasps were collected from the Huron Mountains area, Marquette Count, Michigan during me summers of 1983-1985. Factors affecting the distribution and abundance of some species are discussed.

Cereal Leaf Beetle (Coleoptera: Chrysomelidae) And Winter Wheat: Host Plant Resistance Relationships, Stanley G. Wellso

The Great Lakes Entomologist

The cereal leaf beetle was introduced into North America from Europe prior to 1960. An overview of the control of the insect in North America is presented with major emphasis on host plant resistance. The length and density of the adaxial trichomes (pubescence or leaf hairs) convey resistance to wheat, and the amount of resistance can be estimated mathematically without the insect being present.

Field Tests Of Kairomones To Increase Parasitism Of Spruce Budworm (Lepidoptera: Tortricidae) Eggs By Trichogramma Spp. (Hymenoptera: Trichogrammatidae), Daniel T. Jennings, Richard L. Jones

The Great Lakes Entomologist

Hexane extracts of spruce budworm, Choristoneura fumiferana, moth scales, applied at 0.04 moth-gram equivalents/branch and at 0.06 moth-gram equivalents/tree, failed to increase parasitism rates of Trichogramma spp. in two cutover spruce-fir stands in Maine. Releasing "Maine-strain" T. minutum apparently increased parasitism rates about 20-fold. However, application of kairomone extracts to whole branches and to upper crowns of small trees may have interfered with host-searching behaviors of Trichogramma parasitoids.

Collecting, Rearing, Shipping, And Monitoring Olesicampe Benefactor (Hymenoptera: Ichneumonidae), A Parasite Of The Larch Sawfly, Pristiphora Erichsonii (Hymenoptera: Tenthredinidae), A. T. Drooz, L. C. Thompson

Procedures are described for collecting, rearing, shipping, and monitoring the intro- duced ichneumonid, Olesicampe benefactor, a valuable parasite of the larch sawfly, Pristiphora erichsonii.

Parasitism Of Ancistrocerus Antilope (Hymenoptera: Eumenidae) By Leucospis Affinis (Hymenoptera: Leucospididae), David P. Cowan

The Great Lakes Entomologist

The chalcid wasp Leucospis affinis has been known to parasitize only megachilid bees. Its rare occurrence as a parasite of the eumenid wasp Ancistrocerus antilope indicates that eumenid wasps may be a large resource this chalcid is not exploiting.

Records Of Dufourea Maura (Hymenoptera: Halictidae) From Isle Royale National Park, Michigan, Michael S. Arduser

The Great Lakes Entomologist

Dufourea maura is recorded from Isle Royale National Park, Michigan. This is the first report of this western North American species east of the Great Plains states.

Honeylocust Twig-Gall Midge (Diptera: Cecidomyiidae) In Michigan, C. G. Wertheim, H. L. Morton

The Great Lakes Entomologist

Emergence and oviposition data were gathered for Neolasioptera brevis, a recently described pest of honeylocust. In 1984 the insects first emerged on 21 May and first oviposited on 4 June; in 1985 they first emerged on 28 April and first oviposited between 5-20 May. Average raceme length at emergence and at oviposition were 2.7 and 4.4 cm in 1984 and 2.6 and 4.8 cm in 1985. Approximate duration of the emergence period was one week. In 1985 observed oviposition wounds averaged 0.5/cm.

Impact Of The Poplar-Gall Saperda, Saperda Inornata (Coleoptera: Cerambycidae) On A Hybrid Populus Plantation In Michigan, Lincoln M. Moore, Louis F. Wilson

The Great Lakes Entomologist

Saperda inornata attacks on hybrid Populus were monitored in a stand for four years after planting. More than 60% of the whips were attacked the first year, resulting in a mean of 1.6 galls/tree (range 0-8). Branch attacks superseded stem attacks in the third and fourth years. Saperda injury significantly reduced height because of leader breakage after the second-year attacks, but the injured trees grew rapidly and recovered much of the height in the third and fourth years. Saperdas killed 4% of the trees during the study, but this was no more than would be expected in a newly established …

Ecology Of The Cerambycidae (Coleoptera) Of The Huron Mountains In Northern Michigan, D. C. L. Gosling

The Great Lakes Entomologist

Eighty-nine species of Cerambycidae were collected during a five-year survey of the woodboring beetle fauna of the Huron Mountains in Marquette County, Michigan. Host plants were determined for 51 species. Observations were made of species abundance and phenology, and the blossoms visited by anthophilous cerambycids.

Pitfall Trap Collections Of Ground Beetle Larvae (Coleoptera: Carabidae) In Kentucky Alfalfa Fields, R J. Barney, B. C. Pass

The Great Lakes Entomologist

Pitfall traps were installed in alfalfa fields to monitor the seasonality and abundance of immature ground beetles. Head capsule widths were determined by instar for Evarthrus sodalis, Harpalus pennsylvanicus, Chlaenius tricolor, Scarites subterraneus, Amara cupreolata, and A. impuncticollis. Seasonality of larval and adult catches indicated that E. sodalis, H. pennsylvanicus and A. impuncticollis overwinter in a larval diapause while A. cupreolata and S. subterraneus overwinter in the adult stage.

Biology. Ecology, Larval Taxonomy, And Distribution Of Hydropsychidae (Trichoptera) In Wisconsin, Kurt L. Schmude, William L. Hilsenhoff

The Great Lakes Entomologist

About 43.000 larvae and 1800 adults of Hydropsychidae from Wisconsin were studied. These included Diplectrona modesta, Macrostemum zebratum, Parapsyche apicalis, Potamyia flava, eight species of Ceratopsyche, and 11 species of Hydropsyche, but because their larvae cannot be identified the nine species of Cheumatopsyche known from Wisconsin were not included. Keys were developed to separate larvae of species of Ceratopsyche and Hydropsyche that were collected in Wisconsin or are likely to occur here, and notes are provided to facilitate identification of closely related species. Two forms of Ceratopsyche morosa are distinguished, and the larva of Hydropsyche pIacoda is described. Most …
